A 5.00 kg package slides 2.80 m down a long ramp that isinclined at 24.0° below the horizontal. The coefficient of kinetic frictionbetween the package and the ramp is mk = 0.310. Calculate (a) thework done on the package by friction; (b) the work done on the packageby gravity; (c) the work done on the package by the normal force;(d) the total work done on the package. (e) If the package has a speedof 2.20 m/s at the top of the ramp, what is its speed after it has slid2.80 m down the ramp?

Question
A 5.00 kg package slides 2.80 m down a long ramp that is
inclined at 24.0° below the horizontal. The coefficient of kinetic friction
between the package and the ramp is mk = 0.310. Calculate (a) the
work done on the package by friction; (b) the work done on the package
by gravity; (c) the work done on the package by the normal force;
(d) the total work done on the package. (e) If the package has a speed
of 2.20 m/s at the top of the ramp, what is its speed after it has slid
2.80 m down the ramp?
